Reflecting and refracting telescopes both have their own unique set of pros and cons that make them better or worse for different situations. Difference between Reflecting and Refracting Telescopes Refractor Telescope kits are also available, which allow amateur astronomers to build their own telescopes. Prices range from less than $50 for a small handheld model to several thousand dollars for a large research telescope. Refracting Telescopes are available for purchase through scientific supply companies and retail stores that sell optical equipment. Glass lenses are also more expensive than plastic lenses. Glass lenses are heavier than plastic lenses and require more precise alignment in order to function properly. MostRefracting Telescopes use a glass lens, but a few use a plastic lens.Binoculars are a type of Refracting Telescope. Refracting Telescopes are also used for terrestrial (land) viewing. This type of telescope is well suited for astronomical observing because refractors do not produce the “sparkling” effects seen in some reflecting telescopes.Refracting Telescopes produce an upside-down image, so many models include a diagonal mirror that reflects the light path 90 degrees. The eyepiece, which is located at the back of the telescope, magnifies the image produced by the objective lens.The lens at the front of the telescope is called the objective lens. Most Refracting Telescopes have an adjustable tube that allows the user to change the telescope’s magnification or power. Refractors come in a variety of sizes, from simple hand-held models to large research telescopes.
